This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

That being said, I've queued this up for the 3.0 and 3.1 stable releases

the whole patch to stable@vger.kernel.org.

you want it applied there, please provide the backport to the above
mentioned email address.
